Crime scene investigators oversee a myriad of complex crime scenes such as armed robberies, home invasions, homicides, sexual assaults, and other property crimes. The CSI created a crime scene perimeter before investigating. CSI is responsible for collecting, documenting, securing, and properly storing all of the evidence found at a crime scene. Processing a crime scene can be a tedious process that takes several hours, and CSIs must pay careful attention to every detail to avoid overlooking critical evidence. The entire scene can and will be photographed, either by the CSI, as the evidence is collected. CSIs must follow strict protocols for collecting trace evidence such as hair, fibers, glass, paint, or dirt in order to maintain integrity of the chain of evidence. They record each item that found, including its location and any other pertinent information, and catalog and seal the item for transportation to the lab.…

Science plays a major role in the story line of NBC’s police-procedural drama, Law & Order: Special Victims Unit; more specifically, forensic science. From beginning to end, the characters depend on the use and their understanding of forensic science to uncover the mysteries of each examined case. The advancements in technology along with the psychological approach used by detectives to solve each case make the serious and critical role that science plays more than evident to the audience.…
The CSI Effect refers to a supposed impact of the popular CBS crime drama CSI: Crime Scene Investigation. This TV trend increases the expectations of victims’ and jury members’ concerning forensic evidence and the level of crime scene investigation. CSI creates unreasonable expectations on the part of jurors, making it more difficult for prosecutors to obtain convictions. After watching a great number of CSI episodes, it…
The CSI Effect, “ which is most often refers to the belief that jurors have come to demand more forensic evidence in criminal trials, thereby raising the effective standard of proof for prosecutors. While this belief is widely held among American legal professionals, some studies have suggested that crime shows are unlikely to cause such an effect, although frequent CSI viewers may place a lower value on circumstantial evidence” ( Kim, Young S; Barak, Gregg; Shelton, Donald E 2009).…
As crime scenes investigators, there are many different types of death that are investigated day in and day out. Some deaths are classified as natural, undetermined, accidental, suicidal or murder. Depending on the scene and classification, investigators will know how to handle each case. Also depending on the jurisdiction, the cases are investigated by medical examiners, medical examiner investigators or even special units dedicated for specific cases. This paper will explain the different types of deaths, how they are investigated and how they are caused.…
Dr. Edmond Locard’s Exchange Principle states, “Any action of an individual, and obviously the violent action constituting a crime, cannot occur without leaving a trace.” It is hard to say Locard’s Exchange Principle was not disregarded. After three months of expert investigation it was found that the DNA evidence that was discovered at the scene did not belong to Jennifer or Noura. Also Noura’s own DNA was not found at all at the scene of the crime. It is very hard to understand how Noura could have made extreme violent contact with her mother and not left any fingerprints, footprints, hair, skin cells, blood, bodily fluids, pieces of clothing or fibers behind. This lack of traces evidence sets off two different paths in my mind. One way leads you down a road of pure hatred for a parent. Everyone was felt this way one time or another in their life, where a disagreement or argument over something that is usually aimed at protecting the youth, leads to a massive outburst or feeling of rage, that is always immediately followed by guilt or remorse by a normal human being. But what happens when this rage affects a “not so normal” child. One with malice aforethought, that is just so tired of being controlled that they premeditate a murder and thoroughly clean any trace of evidence. The other path is the road Noura’s defense took. She is irrefutably innocent and Jennifer’s killer/killers are still on the loose.…
There are certain crimes that a crime scene investigator investigates. However, they are not limited to a certain type of crime. Yet, most of their cases consist of murder, sexual assaults, armed robberies, home invasions, suicides, fires, auto thefts, auto accidents and any type of violent crime (crime-scene-investigator.net. n.d.). Therefore, most of the crimes they investigate are crimes that causes death, serious injury or high in value. However, they can investigate other crimes within their area of expertise in order to help other agencies solve a…

The clause “A well-regulated Militia, being necessary to the security of a Free State (Constitutional Convention, amendment II)” barley announces a purpose. It doesn’t limit or expand the outlook of the clause “the right of the people to keep and bear Arms, shall not be infringed. (Constitutional Convention, amendment II)” The clause’s text and history merely states that it connotes a citizen’s right to keep and bear arms. The military consisted of all males that was capable of acting together to form a common defense. The Antifederalists was in fear that our federal government would take away the firearms of the people in order to stop citizen militias, therefore allowing a political standing army or to select a certain militia to rule.…
